DEVICE FOR ADVAN'CING BANDSOF MATCH CARDS IN MACHINES FOR THE MANUFACTURE OF MATCHES.

Application filed May 23, 1927, Serial No. 193,747, and in Austria November 11, 1925.

In machines for the manufacture of matches from bands of cards, the action of all the devices such as the device for punching the tongues forming the matches, the device for setting the matches, the device for forming the match heads (dipping device) and the device for dividing the card band into single pieces, depends on the feed or advance of the card band being always effect-ed to one and the same amount, preferably to the amount equal to the width of a match. For instance the setting will be uniform only when all the matches are in the same position opposite the setting members at the moment of setting. According to the invention, an always uniform advance of the match card band is ensured by means of rotating pin wheel which cooperates with a series of holes provided in the match card band and arranged at intervals apart equal to the amount of the feed. The holes are preferably arranged at a distance apart equal to the width of the match, and are provided at the points at which the matches hang to their holding strips. The arrangement of holes at these points is known in itself, but onlyfor the purpose of weakening these places, in order to facilitate the tearing-off of the matches. The utilization of the series of holes for the purpose of advancing the match card band has not been however suggested up to now, although this kind of advance of feed is used already in entirely different branches of industry.

The drawin shows by way of example a construction according to the invention.

The advance of the match card band a is effected by means of a pin wheel 6, the pins 0 of which are arranged in the form of a ring on the c cumference of the wheel. At the points where the matches d are attached to their holding strip, the card band a is provided with holes 7 with which the pins c of the pin wheel 6 engage when the latter is rotating, and thus ensure the uniform advance of the card band to the exact extent of the width of a match. The driving of the pin wheel Z) is taken from the spindle g which transmits its motion by means of the pair of gear wheels 2', 7i to the spindle is of the pin wheel 7). The holes f for the advance of the match band a could also be arranged at some other point, for instance in the holding strip, and at a greater distance apart than that shown in the drawing.

in the setting device illustrated in the drawing, the previously cut matches (1 are set by means of spring controlled pins 8 adjustable in rotating wheels 1 The pins 5 produce of course a uniform setting only when the advance of the match card band takes place in such a manner that the matches are brought opposite the pins at the setting point always in exactly the same position. This condition is fulfilled by the apparatus according to the invention.

We claim A device for advancing match card bands to be used in machines for the manufacture of matches, including in combination with acard band slit along one marginal edge to form match stems and having a row of holes adjacent to the other marginal edge spaced apart a distance corresponding to the distance of the advance and adapted to facilitate the subsequent tearing of the stems, and a rotatable pin-wheel having needle shaped pins extending radially from the periphery thereof and spaced corresponding to the openings so that the pins during the rotation 59 of the pin-wheel engage with the holes and advance of the match card band.

In testimony thereofwe have ai'iixed our sign atures.
